TEMPORARY BINDER OR LOOSE-SHEET HOLDER.

This invention relates to improvements in' temporary binders or looselsheet holders.

An applicationfor Letters Patent on these improvements was filed inGreat Britain on October 29, 1909, No. 24,936.

The main objects of `this invention are,

Afirst, to provide in a temporary binder or loose sheet holder animproved adjusting mechanism for the binding cords or strips, wherebyt-he leaves or sheets are effectively clamped, and one which is of rapidmanipulation. Second, to provide in a temporary binder, or loose sheetholder, an. improved back strip supporting means. Third, to rovidc in atemporarybinder or loose s eet holder, an improved means for locking thebinder to prevent its unauthorized adjustment or manipulation for theinsertion or removal of sheets or leaves. Fourth, to provide an improvedconstruction of binding strips. Fifth, to provide an improved binder inwhich the binding strips may be readily renewed. A

Further objects and objects relating to structural details, willdefinitely appear from the detailed description to follow.

l accomplish the objects of my invent-ion by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention, is clearlyillustrated in the accompanying drawing, forming a part of thisspecification, in which:

Figure 1 is a detail inside view of a structure embodying the featuresof my i'nvention, the cover lids being shown open, the leaves beingshown in conventional form and parts being broken away to showstructural details. Fig. 2 is a detail longitudinal section taken on aline corresponding to line 2--2 of Fig. 1, showing the structuraldetails-of 'the adjusting mechanism. Fi 3 is a detail longitudinalsection throng -tlfe Icover 2, taken' on a line corresponding toSpecification of Letters Patent.

Application filed October 28, 1910. Serial No. 589,554.

line 3-3 of Fig. 1, showing structural details of the step by steadjusting mechanism. Fig. 4 is a detai transverse section taken on aline corresponding to line 4-4 of Fig. 1. Fig. 5 is a detaillongitudinal section taken on a line correspondin@f to line 5 5 of Fig;1, showing the catch for holding the back strip in its retractedposition.

ln the drawings, similar reference characters refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the 'ends of' the sectionlines.

Referring to the drawing, the covers l and 2 are provided with chambersto. receive the adjusting mechanism for the binding strips 3, which arearranged through the inner ends of the covers to project into thechambers, and the back strip 4t which telescopes into' the chambers, asillustrated. Sheetclamping bars 5 are provided, the clamping bars beingpivotally -mou-ntedon the hinge members 6, projecting inwardly at theinner endsv of the covers. The binding strips 3 are arranged throughthese clamping bars. The cover chambers are provided with lids in theirinner walls, the lid for the cover 1 being preferably made up ofsections 7 and 8, the section 7 being hinged to the cover wall at 9, andthe section 8 being hinged to the section 7 at 10. Hinges of thes-o-called piano cover type are shown. The lid- 11 is hinged at 12 tocover 2, a butt-on 13 being provided for retaining the lid in its closedposition.

The binding strips are preferably supported on the cover 2 to beadjusted therein,

a step by step. The mechanism for accomthe binding strips by means ofthe screw 18 supported in lsuitable bearings 19 and 2O in the chamber ofthe opposite cover. This screw 18 coacts with the nut member 21 eff" thecross bar ,22, to which the bindingsti'ips are secured. The screw isprovided with an screw is turned until the nut memberA is rev leasedtherefrom, the binding strips lare pulled apart, thespring is :put'under tension so that when the covers 'are againv moved towardeachb'th-erfthe spring. takes up the slackin, the back strip and alsomoves the member 21 into'cengagement with the threadi out, the outerbars 17 and 22 at strips toeach other.

ed portion of the screw, so that by merely turning the screw, thebinding tension is applied to the binding strips. To prevent this springclosing up the blnder while it lisbeing manipulated, for .the insertionor removal of leaves, I'provide'a spring catch 27 which engages overtheedgeof the plate 28 I on the back'strip, Iwhen it is in its retractedposition, and retains leased. f

To facilitate'the ready attachmentand rcmoval of the binder strips, Iprovide them with attaching pieces 29, having slots 30 therein adaptedto be engaged over the studs 31 on the cross pieces 22, when presentedtransversely thereto. To prevent a twistin movement of these attachingpieces 29 when tension on the binding strips is'released, I providesprings 324 which are mounted on it until the spring-is restuds 33 toengage the Shanks of the studs.

31. The lid for this cover is rovided with a lock 34 on the section 8,the olt of which engages with the keeper plate 35 `when the lid islocked. Section 8 is preferably provided 'with a support 36 adapted toclose into the key opening 37 when the lid is closed, thus preventingmanipulation of the binder adjustin mechanism until the lid is opened.The bin ing strips, designated generally by the numeral 3, are formed oftwo parts, the inner part 38 being shorter than the outer part 39, theparts being secured together by their ends only, as by the stitches 40,so that when the binding strips are straightened part 39 is slackened.This is shown somew Thebinding strips are connected to the cross pointsbeyond the points the layersof the binding As shown in Fig. 1, theextreme ends of of attachment of the attachments are at the bindingstrips. that as these binding strips are of considerable thickness, inorder to secure thedesired strength and body, when they are bent theirGpner sides have a tendenc to roughen or to comefjcorrugated, whioroughening or at exaggerated in Fig. 7.l

The object of this is corrugating interferes with the slipping of the'leaves on the binding strips. This is quite eectively remedied by thusforming the binding strips.

I have shown my improvements as applied to a binder having bindingstrips, and a general structure simllar to that shown in the patent toHarry F. Bushong, No. 851,276, dated April 23, 1907, as I haveparticularly adapted them to such a binder. I desire, however, to remarkthat my improvements are capable of being adaptedy to other or differenttypes of binders, and I desire to be understood'as claiming the samespecifically, .as illustrated, aswell as broadly within the scope of theappended claims.
